This endpoint creates a new Replica that can be used to generate personalized videos. 

The only required body parameter is `train_video_url`. This url must be a download link such as a presigned S3 url. Please ensure you pass in a video that meets the [requirements](/sections/troubleshooting/training-video-size) for training.

Replica training will fail without the following consent statement being present at the beginning of the video:
> I, [FULL NAME], am currently speaking and consent Tavus to create an AI clone of me by using the audio and video samples I provide. I understand that this AI clone can be used to create videos that look and sound like me.

Learn more about the consent statement [here](/sections/troubleshooting/consent-statement).

Learn more about training a personal Replica [here](/sections/replicas/personal-replicas).


Create Replica

This endpoint returns a single Replica by its unique identifier. 

Included in the response body is a `training_progress` string that represents the progress of the Replica training. If there are any errors during training, the `status` will be `error` and the `error_message` will be populated.


Get Replica

This endpoint returns a list of all Replicas created by the account associated with the API Key in use. In the response, a root level `data` key will contain the list of Replicas.


List Replicas

This endpoint deletes a single Replica by its unique identifier. Once deleted, this Replica can not be used to generate videos.


Delete Replica

This endpoint renames a single Replica by its unique identifier.


Rename Replica

This endpoint generates a new video using a Replica and either a script or an audio file. 

The only required body parameters are `replica_id` and either `script` or `audio_file`. 

The `replica_id` is a unique identifier for the Replica that will be used to generate the video. The `script` is the text that will be spoken by the Replica in the video. If you would like to generate a video using an audio file instead of a script, you can provide `audio_url` instead of `script`. Currently, `.wav` and `.mp3` files are supported for audio file input.

If a `background_url` is provided, Tavus will record a video of the website and use it as the background for the video. If a `background_source_url` is provided, where the URL points to a download link such as a presigned S3 URL, Tavus will use the video as the background for the video. If neither are provided, the video will consist of a full screen Replica.

To learn more about generating videos with Replicas, see [here](/sections/video-generation/overview).

To learn more about writing an effective script for your video, see [Scripting prompting](/sections/video-generation/scripting-prompting).


Generate Video

This endpoint returns a single video by its unique identifier. 

The response body will contain a `status` string that represents the status of the video. If the video is ready, the response body will also contain a `download_url`, `stream_url`, and `hosted_url` that can be used to download, stream, and view the video respectively.


Get Video

This endpoint returns a list of all Videos created by the account associated with the API Key in use.

With the Tavus Conversational Video Interface (CVI) you are able to create a `conversation` with a replica in real time.

### Conversations
A `conversation` is a video call with a replica. 

After creating a `conversation`, a `conversation_url` will be returned in the response. The `conversation_url` can be used to join the conversation directly or can be embedded in a website. To embed the `conversation_url` in a website, you can find [instructions here](https://www.daily.co/products/prebuilt-video-call-app/quickstart/).

Once a conversation is created, the replica will automatically join the call and will start participating.

By providing a `callback_url`, you can receive webhooks with updates regarding the conversation state.

Delete Conversation

Create and customize a digital replica's personality for Conversational Video Interface (CVI). A persona defines the replica's behavior and capabilities through configurable layers including:

**Core Components:**
- Replica - Choice of audio/visual appearance 
- Context - Customizable contextual information, for use by LLM 
- System Prompt - Customizable system prompt, for use by LLM
- Layers
  - STT - Transcription, and turn taking settings 
  - LLM - Language model settings 
  - TTS - Text-to-Speech settings
  {/*- STS - Speech-to-Speech settings*/}
  - VQA - Visual Question Answering settings 

When creating a conversation, the persona configuration determines how the replica interacts, processes information, and responds to participants. Each layer can be fine-tuned to achieve the desired conversational experience.

Interactions Protocol Overview

This is an event developers may broadcast to Tavus.

By broadcasting this event, you are able to tell the replica what to exactly say. Anything that is passed in the `text` field will be spoken by the replica.

This is commonly used in combination with the [Interrupt Interaction](/sections/event-schemas/conversation-interrupt).


Echo Interaction

This is an event developers may broadcast to Tavus.

By broadcasting this event, you are able to send text that the replica will to respond to. The text you provide in the event will essentially be treated as the user transcript, and will be responded to as if the user had uttered those phrases during conversation.


Text Respond Interaction

This is an event developers may broadcast to Tavus.

By broadcasting this event, you are able to externally send interruptions for the replica to stop talking. This is commonly used in combination with [Text Echo Interactions](/sections/event-schemas/conversation-echo).


Interrupt Interaction

This is an event developers may broadcast to Tavus.

By broadcasting this event, you are able to overwrite the `conversational_context` that the replica uses to generate responses. 

If `conversational_context` was not provided during conversation creation, the replica will start using the `context` you provide in this event as `conversational_context`.

Learn more about the `conversational_context`: [Create Conversation](/api-reference/conversations/create-conversation)


Overwrite Conversational Context interaction

This is an event broadcasted by Tavus.

An `utterance event` is broadcasted by Tavus at specific times: the user’s utterance is sent when the replica begins speaking, and a separate event for the replica’s utterance is also sent as the replica starts to speak. Each event contains the content of the respective utterance as well as an indication of who spoke it.

An `utterance` includes all of the words spoken by the user or replica measured from when the person started speaking to when they finshed speaking. This could include multiple sentences or phrases.

Utterance events can be used to keep track of what the user or the replica has said.


Utterance Event

You can set up a custom S3 bucket, enable recordings in rooms, and get notified when recordings are ready to be shared.
